MCP3901A0-E/SS Frequently Asked Questions (FAQs)

  • Microchip recommends a 4-layer PCB with a dedicated analog ground plane, and to keep the analog and digital signals separate. Additionally, use short and direct traces for the analog inputs and outputs, and avoid running digital signals near the analog signals.
  • Calibration involves adjusting the gain and offset of the ADC. Microchip provides a calibration procedure in the datasheet, which involves applying a known input voltage and adjusting the gain and offset registers to achieve the desired accuracy.
  • The maximum sampling rate of the MCP3901A0-E/SS is 200 ksps. Increasing the sampling rate will increase the power consumption, but the device can operate at lower sampling rates to reduce power consumption. The power consumption can be estimated using the formula provided in the datasheet.
  • The MCP3901A0-E/SS has built-in overvoltage protection up to 5V, but it's still recommended to use external protection circuitry such as voltage dividers or clamping diodes to prevent damage. For undervoltage conditions, the device has a built-in brown-out detector that can be used to detect and respond to low voltage conditions.
  • Yes, the MCP3901A0-E/SS can be used in a multi-channel configuration. To synchronize the conversions, use the SYNC pin to trigger the conversions on multiple devices. The devices can be connected in a daisy-chain configuration, and the SYNC pin can be used to cascade the conversions.
